AbstractA nonlinear finite element model for geometrically large amplitude free
vibration analysis of laminated composite shallow cylindrical shell panel is presented using high order shear deformation theory (HSDT). The nonlinearity is introduced in the Green – Lagrange sense. The effects of different orthotropic ratios, thickness ratio, curvature ratio and boundary condition are study also frequency ratio (nonlinear
frequency to linear frequency) of cylindrical shell are determined as function of shell amplitude ratio.
